A mounting seat 18 is provided at one end of the air filter 12, and a second connecting bolt 15 is provided on the mounting seat 18, and the second connecting bolt 15 is connected to the second connecting hole 6, and the other end of the air filter 12 is connected to the clamping hole 7. The above structure is a structural form of installing the air filter 12 on the rear cover plate 2. The air filter 12 of the power upgrade model is fixed to the rear cover plate 2 through rubber clamping, bolt connection and air inlet 10, wherein the clamping hole 7 is fixed by a rubber clamping piece, and the second connecting hole 6 is a round hole with a diameter of 7 mm.

[0032] like Figure 5-1 and Figure 5-2As shown, a VCU controller 13 is mounted on the rear cover plate 2, and connecting plates 17 are provided at both ends of the VCU controller 13. Rivets 16 are provided on the connecting plates 17, and the rivets 16 are riveted to the riveting holes 8. A third connecting bolt 19 is also provided on the connecting plate 17 located on one side of the VCU controller 13, and the third connecting bolt 19 is connected to the first connecting hole 5. The above structure is a structural form in which the VCU controller 13 is mounted on the rear cover plate 2. The tram VCU controller 13 is fixed to the rear cover plate 2 as a whole by riveting and screwing. One side of the tram VCU controller 13 is fixed by riveting, and the other side is fixed by riveting and screwing. The fixing effect of riveting is good and the stability is higher.

[0033] The rear cover plate 2 is designed with a universal structure, providing different installation points for various parts and components, making full use of the upper space of the rear cover plate 2 to meet the installation of parts with different functions of various vehicle models, reducing the vehicle model development cost and realizing the platform strategy of different models of the same body.
